冬季或者过渡季节利用室外温度较低空气冷却机房中高发热量的设备是机房节能的理想方式,但是由于室外气候多变,温度不够稳定,冷却通风量的大小不易掌控.为了研究通风换气次数的改变对机房利用自然冷源的冷却效果的影响,现以南京市某典型机房为例,通过数值模拟对不同通风换气次数下的冷却效果的进行模拟分析,最终得出合理的通风换气次数,并据此对机房内部的气流组织进行了数值模拟.

@@@@It’s a energy saving way to use the outdoor air directly for ventilatng the hot equipment of data center in winter and transition season. However, due to that the outdoor climate is changeable and the temperature outside not stable, the ventilation volume is not easy to control. With the typical data center in Nan Jing as an example, the cooling effect in that cooling way under different air circulation ratios is simulated with energy consumption simulation software DeST, and thus a reasonable circulation ratio is acquired, and meanwhile the air distribution in the data center is also numerically simulated with Airpak.
